Expelled SSS-Rank Architect, Rebuilding the Demon Kings Castle!


Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

Johann Grecia belonged to the hero party as an adventurer with the SSS-rank skill [Architect]. He contributed to the suppression of the demon king in his own unique ways. Such as building a guild in the vicinity of the Demon King’s castle, or building a trap house to destroy many demons.

However, on the very day the heroes brought down the Demon King, he was branded as useless, and pressured by the party to leave. Furthermore, all his qualifications as an adventurer have been revoked, and all the constructions he produced with his skill had been taken.

Johann who lost everything, does not care about building with his skill anymore, and is currently camping all alone. Around that time, he encountered a little girl who seemed to have the same idea.

“The Castle of Felukia… It’s completely lost…”

But it seemed that this girl, was the Demon King’s daughter! The castle of Felukia used to belong to the demon king, but the heroes invaded it. It seemed likely that this girl had lost all her relatives. And thus Johann made up his determination.

“Leave it up to me! I, for the sake of Felukia, will build a new Demon King castle!”

“Eh?!” she said as she almost danced in joy. And so Johann promised to build the most beautiful, highest difficulty, most brutal castle for her. “And if the heroes invade the resurrected Demon King castle again, I will repel them with my [Architect] skill!”

The start appears to be quite bad. We have the MC betrayed by generic bad guys who are just created to infuriate the reader and a beta MC who refuses to take revenge on them when given the opportunity. Also the Demon Princess is 5 years old, meaning that the MC might be a lolicon.

This story isn't 'ongoing'- the author hasn't updated it for over a year. I read as far as I did by reading the Japanese originals with google translate.

Bottom line:
Interesting premise, but only so much was delivered and I strongly suspect the author's given up.

Tried reading through the beginning and stopped halfway. The start doesn't appear to be bad, it really is really bad. To throw away basically the strongest post demon lord era skill (basically reconstruction after a devestating war. Japan and Germany didn't get back on its feet by staying in as ruins), it was just done in bad taste. And the reasons for revoking his license also don't make sense. He's revoked from his adventure guild because he stayed in the back lines. What? How does that make any sense? It... more>> doesn't. Personal feelings seem to be the basis of their logic. And it was pretty poorly done. They basically said any logistical support was meaningless. <<less

Well, the start is pretty ordinary, but I still like the idea of this novel and how it goes, it's easy-going and I'm very interested where it will go. Even though there are some questionable moments in MC's past (like why didn't he use his abilities for making an ambush or destroying enemy's infrastructure) still I like this novel.

The reason for the MC being ostracized is a bit off to me and doesn't seem well thought out or delivered. But I am immensely pleased with the interactions between the MC and Demon Princess so far. The struggles of the heroes after MC moves on to Castle Building are also funny.

I feel the story has a lot of potential at this time and I'm looking forward to more humorous developments.

Also, I might be biased because I like cats.
